I am indecisive about buying a product, whether $5 or $1500. Those who know me tend to tell me I'm "bougie." I personally just like to purchase the best quality products at the most effective price. While I do not feel the highest quality items come at the highest price tag, a few items are not worth skimping the money on. This product is one of them. That being said, I'm eternally grateful that I purchased this Roborock S7 MaxV Ultra Robot Vacuum and Mop. As the review headline states - I am very, genuinely impressed. Before trying the Roborock S7 MaxV Ultra, I tried the Shark Ultra 2-in-1 Robot Self-Empty XL. I have no complaints about that robot. I just instantly knew it was not the robot for me. After returning the Shark robovac at BestBuy, I ordered the Roborock S7 MaxV Ultra on Amazon. It got here in less than two days. *INITIAL IMPRESSIONS:* It usually takes a lot to impress me. However, I was instantly impressed with the Roborock S7 MaxV Ultra - including the box it came in. I'm not sure how to explain; however, the preciseness of the edges of the box not only satisfied my OCD nature but also let me subconsciously know that a lot of detail went into the design and packaging of the product. Even the anti-tamper box seal tape included irresistibly satisfying detail. When you peeled the anti-tamper seal tape, the Roborock logo magically appeared in a consistent, diagonal pattern across the sealing tape. Self = SOLD. Disassembling the shipping box was just as satisfying as it was a breeze. The smell of a new electronic is also very pleasing to me - that's what I got unboxing the Roborock S7 MaxV Ultra. Fitted styrofoam protected the entirety of the Roborock robot, docking station, and other parts and accessories that came in the box. *SET UP:* I usually dread setting up new complex devices due to needing to figure out how detailed the process will be. I was (yet again) pleasantly surprised with how simple the setup of the Roborock dock process was. The app was also straightforward to use for setup purposes. Most electronic phone applications can be wishy-washy. That was different from my initial impression of the Roborock app for iPhone. After just under one month of use, my opinion remains the same. The Roborock S7 MaxV Ultra is essentially a plug-and-play style device. All I did was take the robot and dock out of the box, fill the clean water tank with filtered water, and have been using it with ease ever since. *AFTER ONE MONTH OF USE:* I'm still genuinely impressed every time I use this robot vacuum and mop. Usually, the lavender haze stage quickly wears off on me. With the Roborock S7 MaxV Ultra, Christmas is every day around here. I will never be able to clean my floors as well as this robot. It offended me (not really) as I am a true clean freak. It definitely showed me up. The cleaning power is simply outstanding. I love having clean floors every day if I want to. After emptying it for the first time, what really "told" me that this robot vacuum and mop was doing the "tough job" was how dirty the dirty water tank was. After about one week of daily use, I had first to empty the dirty water tank. I have three cats, and the vacuum filter has yet to signal to need to be replaced (I have auto emptying turned to "smart" in the Roborock app). I caution anyone to be aware that the dirty water tank can and will be a bit funky smelling due to the nature of the water - it's dirty water! The same thing goes for the auto wash station on the dock. I decided to use a gentle hypochlorous acid disinfectant spray to clean and disinfect the dirty water tank and the auto wash station on the dock as necessary to avoid any funky smells. The hypochlorous acid cleaner does the deodorizing OK. I have yet to use the OMO Robodock cleaner with the clean water tank. I like to keep things in my house on the natural side - so I'm on the fence about using a dash of the Roborock specially formulated OMO cleaner "here and there" in the clean water tank. The AI obstacle avoidance functions well. I noticed a day ago that the robot seemed to run over a white extension cord. While I did expect that not to happen, I blamed myself for leaving it on the ground while the robot was cleaning. I believe I was doing it for testing purposes. The robot does, however, avoid my iPhone charger and a black extension cord lying on the floor. *THE APP:* The app is relatively simple to use and is a well-designed app. I have not encountered any flaws within the app: no crashing, bugs, or delays. I am using the app on an iPhone. I like that I can tell the Roborock S7 robot which rooms I want to clean, how many times I want them cleaned, when to wash the mop, etc. I am not impressed with the matrix functioning of mapping the floor. I use the 2D and 3D versions of the map, although using either genuinely does not make a difference to me. I have not gotten the chance to really explore all of the features of this Roborock robot or app. However, I am truly finding new features I was unaware of the more I dig around in the app and user settings. Hence, I am continuing to be impressed. I am a huge fan of how customizable the app makes the Roborock S7 experience feel. *WHAT I WAS NOT EXPECTING:* I was unsure about buying this Roborock S7 MaxV Ultra compared to the Narwal cleaning robot a couple of months ago. I was hesitant to buy the Roborock S7 MaxV Ultra because I did not realize sooner that the Roborock S7 MaxV Ultra DOES clean its mop. Suppose I had known that sooner, and I would have it ordered sooner. I am glad I eventually discovered that it does wash its mop. Otherwise, I would have never ordered it. I also did not expect the Roborock S7 to have an LED flashlight to help it see in dark/low-lit rooms. It does not drain the battery life at all. I was also shocked to find out (as mentioned before) the funky smell of the dirty water tank and slightly from the auto wash station. You must get down close to the auto wash station to smell it. Still, I'm not too fond of that. However, this issue is easily fixable with a bit of cleaning power and maintenance. Lastly, I was not expecting the dock to not come with a dryer module. I was annoyed, although impressed that this is a separate module for purchase that does seem reasonably priced. So, there's that. *LAST COMMENTS:* There are too many pros to this Roborock S7 MaxV Ultra for the cons even to become considerably noticeable. The high price tag initially threw me off. However, after one month of usage, the price is unshakeably justifiable. The cleaning power is phenomenal (for lack of a more satisfactory description). This robot vacuum gets five stars and an A+ in my book. I advise anyone I know (and don't know) to try it out. I can't sing my praises enough or loud enough. I am genuinely happy that I purchased this Roborock S7 MaxV Ultra. I understand the S8 has recently announced for launch to come out for purchase. While I'm sure the S8 will impress others, I can not be happier with this one (S7 MaxV Ultra). The S7 and S8 features are not all that different and warrant the purchase of the newer version (in my opinion). There, this thing is the icing on the cake. Very happy customer!

The technology and features of the Saros 20 finally bring everything I need to keep my house clean with minimal effort. Compared to other robot vacuums I have had, it was easy to set up and started cleaning right away. I have had robot mops that did a good job in the past, but the Saros 20 has some features that really make a difference. First, the water used to clean the mop gets hotter, so it is more sanitary and the mop heads do not start to smell bad. Also, the mop will reach closer to the wall which finally cleans all of the floor instead of needing to go back and do manual mopping. Also, the mop pads are higher quality and I noticed a cleaner floor after the first mopping. The vacuum is also clearly better than anything else I have tried. The suction picked up more dirt and I notice the carpets are cleaner. I didn't need to program or set up anything. The Saros 20 detects the carpets and tiles. It automatically drops the mop pads off when it goes to vacuum, so there is no dragging the mop over the carpoet and it is able to stay close to the carpet to clean even better. The navigation is also a big upgrade. The best vacuums I have tried before had rotating lidar on the top. But that made the robot taller and sometimes would fail or need to be cleaned. The Saros 20 has the navigation on the front and sides, so the robot is much shorter, closer to the ground, than others. The new imaging technology is also great at seeing obstacles and understanding where it is going. It does not bump into anything and even knows how to climb over small objects. Amazing! It knows how tall it is and sees the height of furniture. It does not get stuck under things or go places it cannot get out of. The mapping was fast and made a better picture of what the house layout is. I have not used the furniture or curtain features, but it will even keep track of where the furniture is. It even takes pictures of my dog if I ask it to. Fun! I was also impressed with how fast it finished cleaning. It spends less time figuring out where to go and just gets the job done. It doesn't waste time re-cleaning areas, backtracking, or trying to free itself from tight spots. It moves from room to room, finishing entire floor faster than my previous robots. It is also quieter than anything else I've seen. The combination of stronger suction, deep mopping, and fast, intelligent navigation makes this a pleasant, frustration-free cleaning experience. I don't think anyone should hesitate. This is how robot vacuums are meant to be.

I bought two S7 MaxV Ultras; one for upstairs and one for downstairs. I was skeptical of the robots and had low expectations. Boy was I wrong! I have hardwood floors and bought the robots because I have two cats; I wanted to vacuum all the fur they shed and all the cat litter they track. The cat litter I use is granular, with each granule about the size of a grain of sand. I didn't think that a robot vacuum would be able to suck up this sort of debris. To my surprise, the S7 MaxV Ultras were easily able to vacuum the cat litter as well as other debris on the floor. And the robots were great at mopping too - they cleaned all the accumulated dust/dirt off my floors. I also purchased two mop driers for the Ultras and they work perfectly. Pros: * Powerful suction while vacuuming, able to pick up cat litter. * Mopping worked flawlessly, cleaning all the accumulated dirt from my floors. * Nice app. Using the app I was able to update firmware, configure cleaning options, control whether or not I wanted the camera to be available online (I wanted this feature enabled), and define a no-go zone (I didn't want the robot to clean underneath a reclining chair I have because I put double-sided tape under the chair to deter my cats from this area. Cons: * Not able to completely vacuum/mop all areas of my condo. Some areas are simply too confined for the robot to fit into. Obviously these areas aren't going to be cleaned - under drapes, areas boxed in by furniture, stairs, etc. This isn't a flaw of the S7 MaxV Ultra per se - it applies to all robot cleaners. If the robot can't fit into an area, it won't be cleaned. * Terrible user manual. After reading the user manual I still had no idea how to use the robot. * App a bit unintuitive. After installing the app, I wasn't sure how to proceed. I ended up trying each menu option to see what it did and was able to figure it out after a while. For the most part the app is good, but improvements could be made. For example, when renaming a map, the application hung. After restarting the app, the map was renamed and all was well - but why did it hang? Another example - you can rename your robots using the app, but doing so isn't obvious at all. I eventually found the rename functionality hidden under one of the menu options - going from memory maybe it was under "Product Features" or somesuch. * Roborock cleaning fluid contains oil which is toxic to cats. I was going to purchase their cleaning fluid but fortunately I read the negative reviews of this product. Not only is their fluid toxic to cats - it apparently causes mold/slime to grow. I'm using pure tap water to mop, and this is working out perfectly. * No app for PC/Mac. The app used to control the robot is for iPhone/Andriod. This is OK, but it would have been even better if an app were available for your PC/Mac so that you can control/monitor cleaning while working on you PC/Mac, even if your phone is being recharged. I'm giving the S7 MaxV Ultra Robot Vacuum 5 stars because I'm extremely happy with the robot. Even so, improvements could be made.

I never post reviews, but tonight, I feel absolutely compelled to share my story. I have been over the moon with how great this machine is. Great vacuum, great mop, really clean floors! It does everything so great! Except one MAJOR thing that it doesn't do...although the manufacturer claims it does: it will NOT avoid dog poop. With all of this technology onboard, if your dog messes in the house--and the vacuum runs before you find the land mine--you are in for a huge mess! The BIGGEST selling point of this machine for my family was that it would be great to keep the house clean having three dogs. And that is so true. It's been great! But, our oldest dog (we have three) has become incontinent in her old age, so we have accidents from time to time. If you read the description of the machine, one of the biggest selling points is object detection. And, while the object detection is mostly really good...it only takes one horrible accident to become an incredibly bad situation. The manufacturer, I'm sure, will try to claim that the size of my dog's poop was probably too small to be detected. And I'm sorry, but I STRONGLY disagree! I believe they claim the object detection is supposed to be an inch tall and two inches wide (minimum for detection). I wish I took a picture of the mess...but I CANNOT explain how majorly mad I was. I'm only NOW writing this after cooling off. In hindsight, I KNEW we might have an issue when I noticed, one night, that the vacuum was bumping into the dog's bones and toys. These bones are about 2 inches in diameter, and easily 4/5 inches long. That is ABSOLUTELY big enough for this machine and all of its sensors and tech to recognize...and yet, I watched this machine just bump and push the bone around like it wasn't even there. The dogs also have a round ring chew toy that sits about 1 1/2 inches tall and a good 6/7 inches in diameter. With this toy, the machine just drove over the top of it. According to another reviewer on here that had a similar issue, he mentioned that the manufacturer documentation states that liquids or dog waste will void your warranty. I will be researching that asap! I find it VERY hard to believe that the exact situation that they claim will NOT happen will actually void your warranty if/when it does. At any rate, the wife is upset because the smell of poop is now everywhere in the house. Oh! Did I mention that tonight's event wasn't the FIRST time...but rather the second??? The first time--thank God!--I discovered just after the machine ran through the waste. The machine was covered along the side with the rotating brush, and it was packed in all down that side. Thankfully, it didn't spread it all over the carpet. I got to it soon enough. Tonight though? sigh....not as lucky. Tonight, the machine went into the mess, then proceeded to vacuum over our area rug in the living room. The mess and smell will require a LOT of cleaning to take care of it. Again, I have LOVED this machine since I bought it--almost two months ago now--and the promise of having a cleaning machine to keep the floors cleaned of paws prints, drool, pet hair, dander, dust, etc was just phenomenal. But folks...if you have a dog, and you think this will help solve your problem, BE VERY CAREFUL!!! It could create a nightmare if you aren't careful. You've been warned. Fool me once, shame on you! Fool me twice?? Shame on me.

I upgraded to this after my S7 MaxV Ultra finally started having minor issues and got demoted to clean upstairs. For the most part, this is working much better! For reference, I have LVP flooring and a lot of low pile area rugs throughout my house. I also have 3 fluffy dogs and 2 cats, so I run the vac and mop nightly. Pros: - Hair doesn't get stuck around the main brush. I have cleaned the bearings a couple times (it didnt throw an error, this was just me checking out of curiosity), but the hair was minimal, not nearly as bad as my S7 that neededing cleaning every two days. - Quieter than my old Roborock. - Suction seems to be picking up more hair than my old machine. - The self-empty feature is also much better so far, my old one was pretty finicky. - Doesn't get stuck under low furniture as often, though I have had to set a couple "no go" areas still. - The mop cleans better and the two spinning mop heads just seem better quality overall. - Battery life seems good, I have it set to "boost" mode for vacuuming and mopping every night and it never has to quit cleaning to charge. - I like the separate container for the mop cleaning solution. Cons: - The robot docks "backwards," so if I want to check the dust bin for any reason I have to manually pull it out. - The price is a bit extreme, even on sale for prime day. - The plastic top part covering the dust bin area does not lift up like my S7, it just sits on top and you have to totally remove it to get at the dust bin, which is really annoying. Overall, I'm glad I upgraded, and this machine is running more smoothly than what I was accustomed to with my 3-year-old S7 MaxV Ultra. I haven't used the camera or voice control options much other than to confirm they work. I also haven't had the chance to see if the Saros 20 is better at avoiding pet accidents yet, but I'll try to update my review once the inevitable cat puke incident happens.

Let me start off by saying that we have three Siberian Huskies in this house. That is a LOT of fur. We've had a couple of iRobot Roombas over the years, and they helped cut down the amount of time I spent sweeping up fur by a fair amount, but I had grown weary of the issues with them. Firstly, how randomly they wander around the house, the slamming into my furniture (especially chair legs), how freaking' LOUD the thing was when running, what a huge PITA it is to clean fur out of the rollers, etc. I also have problems with my hands that make mopping rather painful. Challenging for someone who has a bit of a "floor thing". I knew there were more advanced robots out there that could do a better job than trusty old Frackin' Toaster (Roomba's name, obvs) and come with more features. When this robot went on sale for Cyber Monday, I went for it. The reviews (here on Amazon as well as other review platforms and articles) were almost universally 5-stars positive, and it seemed to include pretty much everything I wanted in an upgrade. Holy moly y'all, best grand I've spent in a long time. I've had this guy running for almost a month now (because you know I launched him as soon as he was set up), and here are my findings. Pros: Quiet!: SO MUCH QUIETER THAN ROOMBA. I can watch TV if I wanted to with this guy running. People on the other end of my conference calls during the day don't hear it, even if don't have my noise cancelling headphones on. Smart pathing: When I fired it up to do its discovery run, I was amazed at how quickly it performed its initial room discovery. No vacuum running or anything, it just cruised around using LiDAR and other sensors and mapped the heck out of my first floor. On its first full cleaning run, it tightened up its mapping and identified furniture and other items. When it cleans, it performs an outline cleaning of the room and the furniture in it, then cleans the rest of the floors in an efficient and effective pattern. Freakin' awesome. Definitely smarter than a Valheim Troll, unlike my previous Cylons...erm, floor robots. Object detection: With the camera, LiDAR, and other sensors this guy has, it does a fantastic job of object detection. No more damage to my furniture from repeatedly slamming into legs etc. It will make a guess at what it's run into if it runs into something on the floor. Fabric, shoes, cords, whatever it comes across that is 'unexpected'. Funny story - my husband's Chewbacca head slippers were identified as "pet waste" (I assume due to being brown, and about the size and shape of a pile of big dog poo if viewed from ground level head-on) but that's the only oddball identification I've seen. Cleaning around furniture: Okay, this is fabulous. The Roombas are awful at navigating dining table and chairs, stools at the counter, etc. Would spend 30% of its battery life stuck under the chairs. Ser Toaster III rocks at it. Gets aaaaaaaaalll the husky glitter from under the table and without beating the snot out of my chair legs. Mopping: Look, I know I could probably do better on my hands and knees with a bucket, but pass. My entire first floor is ceramic tile and it now gets a nice sponge bath every day. They look and feel quite clean, my socks are clean, and judging by the water I'm dumping out of the tank, ST3 is definitely getting the job done. I love that it goes and cleans the mop frequently rather than dragging a dirty rag around the house. I also bought extra mop pads so I can change them out every other day or so and get them a thorough trip through the washer. Fur removal: Both in removing it from the floors and being able to remove it from the machine, I give it a 12/10. Despite my Husky pack's best efforts, there are no fluff drifts. I still have to bust out the Dyson on the weekly to get the cracks and crannies, but I could probably get away with less often if I was slightly less extra about the fur removal. But seriously? Whoever designed the roller was a frigging genius. Rather than fighting to unwrap the fur from the ends, the ends just twist off so you can slide the whole fur bundle right off. To whomever designed that roller: I love you. Seriously, I love you. Cleaning the unit: Another win here. The brush assembly that cleans the mop head has a little lever you can flip up to remove the brush and do any fuzz removal or give it a rinse. The filter that catches any debris (leaves, stray fur) lifts right out for cleaning as well. (Learn from my mistake, put a paper towel under it or you're gonna make a muddy mess on your way to the sink). The bin design is also very smart (both for water and for dirt) - super easy to empty and keep clean. Scheduling: I love being able to set different routines and schedules. I work from home, so being able to set the robot to go vacuum my office at 5:45am and subsequently ignore my office when it does its noon run is great. You can set quiet hours where it will do a job, but it will turn down its voice and not empty itself. The office run it does for me is after I've gone to the gym, but before my husband wakes up, so it returns quietly to its dock and doesn't empty itself until it goes to do its noon "daily maintenance" cleaning. This is important because when it does empty the dust bin, it is LOUD AF. But just for about 10 seconds or so. The app: I like that I can view where the robot is, how it cleaned, what the maintenance status is (it reminds me to clean the sensors, clean the filter, etc), any objects detected, etc. See cons for what I don't love. Cons: The app: The app is not particularly intuitive. The routines are in a completely different place than scheduling, for example. That's honestly my biggest beef. App needs a serious UX overhaul. Dust bin bag: This is a disposable vacuum bag. I wish the design didn't require a disposable and non-reusable bag. Carpet: I have a large rug in my office with a fairly low pile. After observing how it does on this carpet, I don't think I would recommend this unit to anyone with plushy carpeting. It uses a rubber roller rather than a brush, and I just don't think it would do a particularly amazing job of grooming the pile. Toaster (the disgraced Roomba) has moved upstairs (AKA No Dog's Land), and I think because of the double roller with an actual brush, it performs better on carpet with any kind of pile. If you just have area/throw rugs with a lower pile or berber type carpet, I think it'll do fine. Throw rugs: Speaking of throw rugs, mixed bag on those. I have a couple it will successfully navigate, but others (like my bathroom rugs) it wants to drag around. I know which ones it'll mess with now, so I pick them up. The ones it doesn't mess with, it really nicely lifts the mop up so you don't end up with a wet rug, then puts it back down once its off the rug. Final verdict: Ser Toaster III is a fantastic floor robot. It's not absolutely perfect, but nothing is. This gets close enough for me to say unreservedly that I would buy it again. If you can swing the cost on this unit (including the recurring cost on the bags and replaceable parts like the edge brush and such), it's totally worth it.

I hate vacuuming. Always have. Unfortunately, in the division of chores in our house, it became my responsibility. So a few years back I got a robot vacuum for xmas, but it was a cheaper one, and it was kinda "meh." Can't remember the brand. It did inspire me to buy a Roborock S4, though, which I loved. Unfortunately, after one too many of my son's charging cords got run over, my S4 finally died around Thanksgiving 2022. Technically, I could have bought replacement parts, but whatever. This was my excuse to upgrade. I did my homework (thank you Vacuum Wars) and opted to stay with the Roborock brand. The S7 Vmax Ultra is way better than I could have hoped! I love the Roborock app. It's easy to use, including setup. I really liked the quick mapping feature on the S7. It allowed me to map the house and set up the rooms and barriers/no-go zones quickly. I thought the automatic division of rooms was so-so, I think I ended up redividing them all manually. With the S7, I am using the scheduling feature to ensure that it runs regularly, as opposed to manually starting the cleaning like I did with the S4. I did not think I'd like the automatic dustbin emptying as much as I do. With my S4, it always felt good seeing the amount of dirt collected when I ran it. However, as my wife pointed out, that always led to a dust cloud on top of the trash can when you threw anything else away, which we don't have now since the S7 dust is all contained in a disposable bag. I did a few unofficial tests with the mop on my kitchen floor. My overall impression is that it is a pretty decent mop. I used to Swiffer it like once a month or so, but now I just let my Roborock do the job on Saturdays while we are out of the house. So that was an unexpected win! We are actually going to remove the carpet in most of the downstairs next year (right now my dining room is carpeted...terrible choice if you ask me), so having the mop for our new flooring will turn out to be really nice. One unexpected byproduct of owning a robot vacuum is it's helped train our son to pick up his toys. When we got the S4, he was fascinated by it, so it was easy to tell him, "Pick up your toys so we can run Rob!" After a while it became a habit which has more or less stuck, although I usually do a visual sweep of the house before I leave for work on the days our S7 runs just to be sure. I guess that's a possible drawback of the bag system, there's no finding any little toys or whatever that get vacuumed up. Luckily, he's old enough now that it's not really an issue. So I guess I've prattled on long enough about all the stuff I love about this machine, so it's time do discuss the negatives, as there are a few. Number one is with the auto scheduling feature, it is lacking in a "skip the next scheduled cleaning" button. Recently my wife was home sick for a day, and I had to go in and manually remove Tuesday from the list of days it was scheduled to run as I didn't want to disturb her if she was asleep on the couch. The automatic dustbin emptying feature is LOUD for like 30 seconds. Not really a complaint, just was unexpected. So a "skip cleaning" button would be nice. Next, while the bag system has it's merits, I really do hate buying something just to throw it away. Having a dumpable bin would be a nice option. Also, it would let you see if anything of value was sucked up. I haven't bought any bags (or other replacement parts) yet, but I'm guessing they aren't super cheap. Next, the obstacle avoidance feature is supposed to identify and avoid stuff left on the floor, but I'm unimpressed. I did a test, and it ran smack into a pair of slippers as well as a belt lying in the middle of the room. Also, it wrapped up a charger cord that had fallen off the table. No damage done, but it did stop the vacuuming that day. Pretty small complaint list, if you ask me. This machine is pricey, don't get me wrong. I did save like $400 by getting a black friday deal, but it's still a lot of money for a vacuum. However, the benefits are very much worth the cost if you can swing it. Our house is so much cleaner than it has ever been. When the morning sun shone in the windows, you used to just SEE the dust floating in the air. That is no longer the case, or at least not nearly as bad. Our allergies are not nearly as bothered as they used to be. Once it's set up, you can mostly forget about it. One improvement I forgot to mention is that I like the brush better on the S7 than the one on the S4. It doesn't have bristles, just rubber fins that seem to do just as good of a job without constantly needing the lint cleaned out of them. My wife has long hair, so be aware that you will still need to clean that off of the brush regularly. I do it once a week using a seam ripper I purchased from a fabric store, as the S7 does not include one like the S4 did. So if you are still reading, thanks! I've really enjoyed writing this review. I can't say enough good things about this machine. While it is not perfect, it has taken a chore that I absolutely hated and never did frequently enough and turned it into a job that takes like 10 minutes of effort a week, and minimal effort at that. For anyone wondering, I've been using my S7 for 3 months as of now. Our downstairs is approximately 900 square feet, with about 2/3 of that being carpet. The remainder is a mix of tile and LVT. It has a multi-level function which I used on the S4, but haven't set up yet on this one. Eventually I will do the upstairs and basement as well since it can store multiple maps for different levels of the house. I run the vacuum 3 days during the week and a vacuum/mop cycle once on the weekend. Sometimes I run it more just cause I can. I like to tell people "I think I'm going to vacuum my house now" while we're out doing something, and then show them the app and start a cycle. I know, I'm a nerd. But my house is clean!

Set name: 01_Saros_20
Disclaimer- I did have AI polish my words in this review, but it's very real and I am not a paid sponsor of the product, just a relieved pet mama. If you have a zoo's worth of fur in your house, you know the absolute struggle of finding a robot vacuum that doesn't instantly choke. I have 7 dogs, and after burning through the top major brands, the Saros 20 is the first and only robot vacuum to actually get the job done. Before finding this lifesaver, I tried two other high-end models: The Shark PowerDetect NeverTouch Pro Combo: This was a total nightmare. It clogged constantly, left massive clumps of fur all over my floors, and the app was incredibly frustrating—it only allowed me to set up one routine a day, meaning I couldn't schedule rooms to be cleaned one at a time. The iRobot Combo (j7+/705 series): It promised a lot, but it simply could not handle the sheer volume of fur from my pack. When I first got the Saros 20, it did decent, but because 7 dogs produce a mountain of hair, it did get one initial clog. Instead of giving up, I adjusted my strategy: I scheduled room-by-room cleaning with an automatic bin-empty cycle in between each room. Ever since making that tweak, it has performed flawlessly. Zero clogs. Why I Love It: Smart Scheduling: Unlike the Shark, the app flexibility allows me to break down the cleaning schedule room-by-room so the vacuum doesn't get overwhelmed by pet hair. Remote Video & Two-Way Voice: The camera and voice feature are awesome. It's incredibly reassuring to be able to log in while I'm away, drive it around manually via remote control, and check in on the house and the pups. Whisper Quiet: I set it to run every single night while we sleep. It's quiet enough that it doesn't disrupt anyone, and I wake up to magically clean floors every morning. If you are a multi-pet owner who has been burned by other big-name robot vacuums, save your time and money. The Saros 20 is worth every penny.
